Comparison Analysis of Vinyl Acetate Resins by Using Pyrolysis-GC-TOFMS - MSTips 329
MSTips No. 329
Introduction
As the performance of mass spectrometers has improved, the demand for differential analysis of trace components in materials has increased. To address this trend, we have added a new differential analysis function to msFineAnalysis, our automated qualitative analysis software specifically designed for GC-HRTOFMS data. In this work we used msFineAnalysis to compare Vinyl Acetate Resins that were measured by using Pyrolysis (Py)-GC-MS.
Analysis detail
Two commercially available Vinyl Acetate Resins (adhesives) (A, B) were used as samples. In order to conduct statistical comparison analysis, GC/EI measurements were performed for n=5. As the condition for differential classification, p-value (an index: the smaller the p-value, the higher the statistical reproducibility) ≦5% and fold change (intensity ratio between samples ) ≧1.5 were used to perform differential analysis by using msFineAnalysis. The Table 1 shows the measurements condition details.
